FPGA U1 200 MHz 2.5V LVDS Oscillator

Figure 1-2
The ML630 board has one SiTime 2.5V LVDS differential fixed 200 MHz oscillator per
FPGA. Oscillator U22 (located on the bottom of the board) is connected to FPGA U1 as
listed in
Table 1-10: FPGA U1 LVDS Oscillator U22 Global Clock Connections

FPGA U2 PROG Push Button, INIT LED and DONE LED

Figure 1-2
Pressing the U2 PROG pushbutton (SW11) grounds the active-Low program pin of the
FPGA. The INIT LED (DS54) lights during FPGA initialization. The DONE LED (DS29)
indicates the state of the DONE pin of the FPGA. When the DONE pin is High, the DONE
LED lights indicating that the FPGA is successfully configured.

FPGA U2 User LEDs, DIP and Pushbutton Switches

Figure 1-2
DS30 through DS35, DS37, and DS38 are eight active-High LEDs that are connected to user
I/O pins on FPGA U2 as shown in
any other purpose determined by the user.
